| 3U VPX, 28V input, -40 to +85 deg. C, intelligent 660W Power Supply |
Sunnyvale, CA — PCI-SYSTEMS Inc. , a leading supplier of conduction cooled systems, today announced several VITA 62 compatible high output, extended temperature range Power Supplies, enabling accelerated development of rugged conduction cooled embedded systems.
This 3U power supply works with 85VAC to 264VAC input voltage at input frequencies from 40Hz to 500Hz and isolates the input voltage ground from the output voltage ground. The power supply is conduction cooled, uses poly-phase technology on all voltage rails and can provide up to 660 watts. It is suitable for use in mission critical rugged applications.
[SMART.PSU]PCI-Systems Inc. intelligent power supplies integrate a microcontroller (MCU) for a fully programmable and flexible solution. Intelligent power conversion allows configuration and reconfiguration for different applications. With intelligent power conversion, the power supply becomes a platform solution for Vita 46.11 system management based systems. The power supply can easily be reprogrammed to support different operating limits and control inputs.
